FEED-MIXING MACHINE.

Application filed August 27, 1924. Serial No. 734,447.

To all whom, it may concern.'

Be it known that I, FRANK AsrDEN, a subject of the King of Great Britain, and a resident of Ocean Falls, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Feed-Mixing Machines, of which the follow ing is a specification.

My invention relates to improvements in feed mixing machines, with more particular reference to machines for mixing. poultry, cattle, or other feeds, although it may be used with equal facility for other analogous purposes, and the object of my invention is to devise a machine of this character which is simple, inexpensive, and highly efhcient and the use of which enables such feeds to be mixed thoroughly and expeditiously and which is of the utmost convenience and utility.

I attain this object by the construction illustrated in the accompanying drawings in whicha Fig. 1 is an end view of the machine, in outside elevation.

Fig. 2 is an end view in sectional elevation, taken through the vertical centre line.

Fig. 3 is a front view in sectional elevation, taken through the line 3 3 of Fig. 2.

Similar figures of reference indicate similar parts throughout the severa-l views.

The machine consists of a. mixing chamber 1 enclosed in a casing 2, the chamber having an upper inlet opening 3 and a lower discharge opening 4, which openings are normally closed by doors 5 and 6 respectively mounted at one side of their respective openings by spring hinges 7 and 8 of anyy well-known approved type adapted to maintain the doors normally closed. Through the chamber 1 and centrally of the same extends longitudinally a rotatable shaft 9,v

which shaft projects at its opposite ends exteriorly of the casing 2 and is provided on one end with a pulley 10 and at'its opposite end' with a gear 1l, which'gear meshes with ears 12 and 13 mounted above and below l 1t and rotatably carried in bearings14 and 15 secured to the side of the casing, as shown in Fig. 3. V, j`

' Secured to the shaft 9 within the chamber 1 and suitably spaced a art thereon are two spiders 16 and :17 avring as many radially extending arms 18 and 19 as may be desired; in the drawings each spider has, for the purpose of illustration, six arms Fig. 2. These plates are formed broader at one end than at the other and they are arranged alternately, when the vmachine -is assembled, as shown in Fig. 3, that is, the broad ends of plates 20,22, and 24 are at the left hand side of the machine when in the position shown in Fig. 3, and the narrow ends of plates 21, 23, and 25 are at the right hand. The plates are also arranged to he at their narrow ends closer tothe shaft than at their broad ends so that their edges are therefore angularlyinclined .with relation to the shaft axis.

Mounted over the opening 3 is a hopper 26 which may, if preferred, beasubdivided into a plurality of chambers by partit-ions 27 so that each chamber may be filled with an ingredient different from those in the other chambers; such subdivision, however, is optional. n

Any suitable means for opening the respective finlet and discharge doors 5 and 6 may be employed, such as an arm 28 secured to the outer face of the gear 12 which contacts at predetermined intervals in the rotation of the gear with an arm 29 extending at its outer end, as at 30, through a slot 31 inthe side of the machine and connected at its inner end to the underside of the inlet door, as at 32, thus moving the arm 29 along the slot and drawing the door 5 downwardly, the spring hinge 7 returning the door to the closed position when the arm 28 passes the end 30 of arm 29. The outer end of arm 29 is preferably fitted with a roller 33 on which vthe arm 28 rides when in contact therewith. The gear 13 is also provided with an arm 34 arranged to Contact atpredetermined intervals in the 4rotation of the gear with a lateral extension 35 secured to the discharge door 6 and depress the same, thus opening the door, which is returned to its normal closed position when the arm 34 passes the ,extension by the spring hinge 8..

of the respective gears one to the other.

The foregoing description of the door opening and closing means is, however, merely illustrative; there are other well-known and obvious means of eecting thelopening and closing movements any of which may be' employed. v

The manner in which the machine operates and its utility will'be readily understood, as it will be seen that on rotating the' shaft 9 by means, say, of a belt drive connected to pulley 10 the mixing plates 20, 21, 22, 23, 24 and 25 and the Oears 11, 12 and 13 will b'e caused tov rotate and feed ingredients will be admitted into the chamber 1 fro-m the hopper 267a1nd discharges therefrom at predetermined intervals as the 5 and 6 respectively open and close. Due to the alternate and inclined. arrangement of the mixing blades, as hereinafter described, the ingredients discharged from the hopper are not only carried around by the plates but are in addition thrown in towards the centre of the machine so that a thorough mixing is effected due to the combined rotary and lateral movements to which the ingredients are subjected so that the feed is discharged from the chamber in a perfectly mixed state.

From the foregoing it will be seen that I have devised a simple, practical, and eiiicient machine the use of which enables poultry, cattle, or other feeds to be thoroughly mixed with the utmost facility and convenience.

What I claim as my invention isi 1. A feed mixing machine comprising, a mixing chamber having an upper inlet opening and a lower discha-rg opening, doors for each opening normally closing them, a plurality of equidistantly spaced circumferentially arranged longitudinal blades rotatable wit-hin said chamber each broader at one end than the other, alternate blades being reverse-ly disposed to the other blades with reference to theirV broad and narrow ends, and means automatically operative to open the respective doors at predetermined intervals in the rotation of the said blades. v

2. A feed mixing machine comprising, a mixing -chamber having an upperV inlet opening and a lower discharge yfopening, doors for each opening normally closing them each having an extension projecting beyond the end of the chamber, arotatable shaft extending longitudinally through the chamber and exte-riorly thereof atv its opposite ends and provided on .one exterior end witha gear, a plurality ofequidistantly spaced circumferentially arranged longitudinal blades within the chamber carried by saidshaft, and rotatably mounted gears meshing with said shaft gear each 'having an arm arranged to contact respectively with the respective door extensions at a predetermined point in their rotary movement and carry the extensions forwardly an amount sufficient to open their respective doors.

3. A feed mixing machine comprising, a mixing chamber having an upper inlet opening and a lower discharge opening, springpressed doors for each opening normally closing them each having an extension projecting beyond the end of the chamber, a rotatable shaft extending longitudinally through said chamber and exteriorly thereof at its opposite ends and provided on one exterior end Vwith a; gear, a plurality of equidistantly spaced circumferentially arranged longitudinal blades within the chamber carried by said shaft, each blade being broader at one end than the other and alternate blades being reversely disposed to the other blades with reference to' their' bro-adi and narrow ends, and rotatably mounted gears meshing with the said shaft gear each having an arm arranged to contact respectively with the respective door extensions at a predetermined point in their rotary movement and carry the extensions forwardly an amout sufficient to open their respective doors and then pass clear of the extensions.
